To all whom it may concern Be it known that we, JOHN B. Tmzsoorr and RAYMOND C. BUSCH', both citiaens'ot' "the United States, and residentsof St'. Louis,

in the-State-of tMissouri, have invented 'a new and Improved Boat-Propelling Mecha-.

nism, of whichv the. following is. a. full, clear', and exact description. y

Among -the principal objects' which the present inventionv .has in View.. are: to pro-1' videl motor units arranged for. .propelling boats; to provide means forjdemounting'and rmounting units of thev character-ignoti? tioned,.to; augment or diminish the 4 motive power'for propelling boats. or similar ,structures; to provide a multi=nnit prime mover for vessels, adapted -o rte1np'orary installation; to provide units ofthe 'charactermem tioned, arranged' for! propelling shallow-v draft vessels'gto provide means for harness# ing said units'to permit theshifting'thereofy for employment asv aids infsteering the vesselto which they .are applied; andtogpro-V vide meansl for harnessing the units to change the angle of loperationl thereof relatively .to the keel of the vessel to which they are aps plied.

One embodiment of the present' invention I.. is shown in the accompanying. drawings, in4

which- 'Figure lfis asectional elevationot a the present| invention;-Fig.A 2 is a top plan viewv of a 'battery of Hinton-'units 4connected bymeans of an operating harness.

Asseen 1n the Vaccornpanymg` drawings', a

boat. is prepare to receive. motor units ofthe character herein described `by yhavlng` mounted thereon slotted'socket ybrackets 7. The socket brackets -7- are elongated, the socket'g'rooves therein extending above the The'lower 'end of said bracket rests uponan extension of the keel .8, as seen best' inFig. 1 of th'e drawin s. f

`he slots` in the brackets 7 are provided to hold in operative position heavy yhinge. knuckles 9,' which are spaced apartv and con.

nected by a body-10. The` knuckles 9 are provided to receive hinge pins l'11 after the same have been passed through the hinge knuckles 12 which are structurally secured to a casing 13 ywhich forms a housing for the motor14- and driving shaft 15 thereof. The

motor'14 is-shown in the drawings as one- .usually provided, 'so that the casing is attached.

The ldriving shaft 15 issuitably connected With shaft a propeller 16, a bearin for the'short 17 thereof being formed, lng boX 18 set in the rearmost vertical wall ofi the casi-ng. It will be noted l that the diameter ofthe propeller or the spread of' the blades thereof is diminished` beyond` that blades will no text'end below the bottom of the casing 13 nor the keel Sof the boat to which said If `the motor lllis anelectric motor,lpower the .casino 13 by junction box? 20' being provided casing.

From the foregoing, it will befseen'that the shafts 15 and 17, propeller 16, and motor an independent struc-v lture; to wit, the'casi'ng 13, which casing, when .in service position, is' ivotedv upon the usual mountingto extend rom the side or When, now, means isv prothecasing 13 may be swung upon its pivot mounting, it 4is .obvious that the' thrust or pull of. the propeller 16 may, be in a lineat an angle to the keel of the boa't.f. It is obvious-that when under headway, the casing 13 may bemoved on the hinge.` pins 1l toassist the rudder or'other steering gear with which the' boat lis provided. It is" equally obvious that should the boat beat rest at the side-fof wharf. ori pier, the casing@ 13 may be disposedin such position that' when the 'motor 14 is operated, the propellers would move the boat away y from said Wharf yor pier, .and this '.withouti'requiring head- Way for. the boat;

with va stulicover 22.'V The 'cover 221s shown as having a handle 23 to ioo or propelling mechanism for the'boat. By

multiplying the number of brackets 7, provision is made for increasing or decreasingthe number of motor units at will. Thus `it will be found that provision may be made -foraugmenting the propelling power to provide forA eXigencies in a trip, such. as, for instance,l a steamer going up 'a fast-,going stream would. require a greater propulsive power, and therefore larger propellingv fas cilities, than wouldbe needed by the same Ivessel when descending the stream.v It is necessary to the perfect operation of the val rious runits that they should be maintainedA- in mutuallyl parallel relation. 'For this purpose, 'each of the casings 13 is providedwith a pivot pin 24. The various pivot pins 24 are operatively connected by a straightlink bar 25.Vl Preferably the distance between the centers of the perforations in saidlink bar provided to receive the pins- 24, is equalto the distance between the centers of the pins 11. The parallel arrangement of the aXes of the powerv units is thereby secured. I, The movement of said units on ltheir various hinge pins is'produced by either manual or powerdriven means, and preferably each in.- stallation is equipped with a manually-operable mechanism having an auxiliary powerdriven mechanism.

The manually operable mechanism employs primarily a hand-wheel-26, whichis operatively connected with va drum orwinch 27. The winch 27 is arranged to collect and pay out a cable 28, from opposite'sides thereof. The cable 28 is reeved about pulleys v2,9, and is secured'at its opposite ends to levers 30. The levers 30 are connectedfeach with the other and with an intermediate gearv wheel 31 by means of link bars 32, which link bars are pivotally connected to the gear wheel 31. The levers 30 are each connected by means of link bars 33 with the link bar 25 and at the oppositeends thereof.

It will be seen that when in the course of operation the winch 27 is rotated to shift the levers 30, the link bar 25 and the casing 13v are moved .concordantly therewith. Should it be desired for any purpose that the units should remain in the' angular disposition. to which theyv are moved, this is *effectedA by permitting thel latch head'of the core 34 in the solenoid 35 to engage the teeth'of the lwheel 31. lPreliminary to movingthe wheel 31 by ,means of the hand wheel 26 and cable connections, the switch 36 is closed to enervgize'tlie electric circuit embodying the wires 37 and 38, the loattery`39l and the solenoid 35. By thus energizing 'the solenoid, the core and the Vlatch head thereof are drawn `hack from', and out ofengagement with, the wheel 31, to permit the same to rotate in corre- -propellers, while lnot requiring the spondence with the operation of the hand wheel 26 and winch 27. When the power units have been set to the desired angle, then, by opening the switch 36, the -latch head ofthe core 34 engages and locks the wheel 31 in position.

The auxiliary. power driven mechanism abovereferred to embodies an electric motor 40, which ,is introduced 'n the circuit above outlined by means of a switch 41. The switch 41, as indicated by the dotted lines in Fig. 2 of the drawings, may be disposed to complete the circuit embodyingthe solenoid motor 40 is operatively-connected with the intermediate gear wheel 31 by means of a pinion 42, the teeth of which are meshed with the teeth of said gear wheel 31. It will be understood that while there' is not shown in the accompanyingdrawings, nor here described, mechanism for reversing the motor 40, nevertheless, any of th'e well known and conventional mechanisms suitable for this purpose may be employed with this end in view.

l'With a propelling mechanism constructed and arranged as described and as shown in the accompanying drawings, a boat may be navigated in very shallow water. The mulished propellers ,compensates for the loss of power incident to the employment of larger submergence of said larger propellers. Also, by manipulating the power units to swing the 'same on their hinge pins 11, the propelling impulse maybe so directedwith reference to the hull of the boat as to coperate with the rudder of said boat, to vary the course there of. Again, if the boat has been tied or made fast to a wharf or pier', the propelling units may be so swung on their hangings as to draw the boat away from the pier.

.While we havev not lshown or described' in the drawings and specification generating means for supplying power to the motors 14, it will be `understood that anyl known or suitable means may be employed. As indicated labove, we do not wish to confine ourselves to for said prime mover, forming a bearing for saidpropeller, and a pivotal. mounting for said casing; means flexibly connecting said units to maintain the same'in parallel relation; an electric motor; a transmission mechanism'connecting said units and said electric motor, said transmission mechanism v35, while cutting outthe motor 40. The

.tiplicati-on of the power units for dimin 95 names to this specification in the presence of two subscrlbing Wltnesses.
